1. A method for the treatment of clot material within a vasculature of a patient, the method comprising:
positioning an aspiration catheter at least partially within the vasculature proximate to the clot material;
fluidly coupling a first chamber to an aspiration pump;
fluidly coupling the first chamber to a second chamber distal of the first chamber;
positioning a filter within the second chamber;
selectively fluidly coupling the aspiration catheter to the second chamber via a user-actuatable valve positioned between the second chamber and the aspiration catheter;
with the valve closed to inhibit fluid flow from the aspiration catheter to the second chamber, generating negative pressure in the first and second chambers;
after generating the negative pressure, opening the valve via a user actuation such that fluid flow at least partially from the second chamber into the first chamber causes rapid aspiration of blood and at least a portion of the clot material into the second chamber, wherein the filter is configured to filter the blood from the portion of the clot material; and
reintroducing the filtered blood into the vasculature of the patient.
